I wanna play around the creation of a new whole star system. Reading the tutorial the star coordinate should be in Right Ascension / Declination / Distance from the Sun format. But how I known my current coordinates in the Universe? I found a nice spot inside a nebula on the other side of the Milky Way, I set myself on a empty space, look the Sun for the distance (15.827 kpc).

For my location I read both user.cfg and places.cfg (I set a place) and found these parameters: -13803.40627231223, -7676.716420040415, -1013.150708890675

They seems on a X,Y,Z format, there is any way to convert on RA/Dec/Distance? By the way, the zero position is the center of the sun? I found those values when I get there: -6.024792766230421e-021, -5.081753759103468e-021, 1.17121835081117e-020.
